A long-standing and vocal campaigner on the issue, Charles said steps “must be urgently scaled up, and scaled up now”.

Charles issued the plea in his new Ladybird book on climate change co-authored with former Friends of the Earth director Tony Juniper and Emily Shuckburgh, a climate scientist at the British Antarctic Survey.

In the foreword Charles states: “I hope this modest attempt to alert a global public to the 'wolf at the door' will make some small contribution towards encouraging requisite action; action that must be urgently scaled up, and scaled up now.”

Prince Charles hopes his Climate Change Ladybird book will lead to urgent action

The guide is based on the books for children created int the 1960s and 1970s

The book explains the history, dangers and challenges of global warming and explores possible solutions with which to reduce its impact.

Mr Juniper said the Prince insisted the text was peer-reviewed for rigour and he remained “deeply involved at every stage”.

“He wanted to present something everybody can read that cuts through some of the deliberately confusing misinformation that's been put out there over the years, which I know he is very frustrated about,” he told the Daily Telegraph.
